Hyaline cartilage. Light micrograph of a section through hyaline cartilage, a semi-rigid connective tissue. The pink nuclei of chondrocyte cells are seen. The chondrocytes synthesize an extracellular matrix (blue) that keeps them apart from each other in spaces known as lacunae (white). Hyaline cartilage provides structural support in several parts of the body, including the windpipe (trachea) and nose. It also lines the ends of long bones, reducing friction in joints. Magnification: x128 at 35mm size.
